The normal tag's function will be influenced by the factor of the environment conditions, such as the metal or liquid surface. The reading performance doesn’t work well when the normal tag is used on the metal surface. To solve the problem, our company researched and made some special designs for the tag’s antenna to improve the reading performance.

HB-621 are the RFID on-metal tags with high performance which are specialized in being attached on the metal surface. HB-621 complies with the protocol of ISO18000-6B. The RFID on-metal tags we develop can keep perfect reading performance when attached on the metal surface. The tags are widely applied in the asset management, vehicle tracking and articles tracing etc.
